Serenade® ASO fungicide is a powerful tool designed to protect against the effects of soil and foliar bacterial and fungal diseases. Applied at planting or through chemigation, Serenade quickly builds a disease-protection zone around the seed or transplant. As the plant’s roots grow, the beneficial bacteria in Serenade ASO formulated and provided at optimized levels grow with them, expanding the disease protection zone and attaching themselves, like armor, to the roots of the plant. Applied as a foliar spray, Serenade ASO protects crops against diseases such as Botrytis, Powdery mildew, Sclerotinia, Xanthomonas and Erwinia.

Key Benefits

  • Directly attacks diseases in the soil including Pythium, Rhizoctonia, Fusarium and some strains of Phytophthora;
  • Activates plant’s natural defenses by priming systemic responses in the plant;
  • Promotes growth and stress resistance;
  • Can be tank-mixed with other in-furrow products like fungicides or fertilizers;
  • Apply using existing spray or chemigation equipment;
  • Unique mode of action (FRAC code 44) for the best defense against the development of fungicide resistance;
  • Exempt from the requirements of a residue tolerance 

Performance: The active ingredient in Serenade ASO fungicide, Bacillus subtilis strain QST 713, is a beneficial soil bacterium. A master of root colonization, B. subtilis strain QST 713 can quickly build a dense biofilm on plant roots. The biofilm acts as a protective barrier for the roots, shielding them from diseases in the soil, even at the roots’ tips. Safely and comfortably growing in the root zone, the beneficial bacteria in Serenade ASO produce metabolites that: 

  • kill soil diseases,
  • activate plant’s natural defenses,
  • promote plant growth,
  • increase the efficiency of photosynthesis.
